Dead bodies
The Stalinist Purges produced 61 million dead and Mao's Cultural Revolution produced 70 million casualties
Pol Pot and the Khmer Rouge kill up to 6 million with Chinese support. All of these actions done "in the name of the people" to create a better world.
And while it is often said that Hitler was a Christian, the Nuremberg documents clearly reveal the heart of this ruthless man who believed in social Darwinism and had devised plans to completely eliminate Christianity after the Third Reich was firmly established. He wanted to use religion to subvert it for his own political purposes, but he had rejected his Catholic heritage long before 6 million Jews and 5 million non-Jews murdered in this quest for Fhrer worship and absolute power. Hitler, in his scheme of things, was to be the new Christ, replacing the tender hearted weakling followers of the Nazarene Jesus.
Hitler quotes:
You see, it's been our misfortune to have the wrong religion. Why didn't we have the religion of the Japanese, who regard sacrifice for the Fatherland as the highest good? The Mohammedan religion [Islam] too would have been more compatible to us than Christianity. Why did it have to be Christianity with its meekness and flabbiness?
Christianity is a rebellion against natural law, a protest against nature. Taken to its logical extreme, Christianity would mean the systematic cultivation of the human failure.
The heaviest blow that ever struck humanity was the coming of Christianity. Bolshevism is Christianity's illegitimate child. Both are inventions of the Jew.
But Christianity is an invention of sick brains: one could imagine nothing more senseless, nor any more indecent way of turning the idea of the Godhead into a mockery.
Judging by Hitler’s testimony of his life, he was no Christian. Any positive noises he made about Christianity could only have been to tickle the ears of his doting followers.
